Name: Hesperostipa comata Great Basin Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This grassland occurs on the Colorado Plateau and Great Basin. Stands are found on plains, gentle hillslopes, knolls and bluffs, mesa tops, and plateau parks. Substrates are variable and include sand, cobbles, clay loams and silty clay. This association is characterized by a relatively sparse to moderate herbaceous layer (10-40% cover) that is strongly dominated by the cool-season bunchgrass Hesperostipa comata. Low cover of other grasses, such as Achnatherum hymenoides, Achnatherum lettermanii, Aristida purpurea, Elymus elymoides, Pleuraphis jamesii, Poa fendleriana, or Sporobolus cryptandrus, may be present. However, Bouteloua eriopoda is not present. Forb cover ranges from sparse to moderate and may be diverse. Associated species may be diverse and include species of Artemisia, Balsamorhiza, Cirsium, Gilia, Hymenopappus, Lappula, Machaeranthera, and Vicia. Scattered shrubs and dwarf-shrubs may be present with less than 5% total cover. The widespread introduced annual grass Bromus tectorum often contributes significant cover in disturbed stands. Some stands have high cover of cryptogams on the soil.
